Intrinsically flame retardant composite phase change materials with epoxy resin melamine phosphate derivative skeleton for battery thermal safety

Zixiong Zhou, Kexin Liu, Yueyu Zeng, Xinxi Li et autres

Organic phase-change materials (PCMs) are pivotal for passive battery thermal management, but their deployment is hindered by intrinsic flammability, molten leakage, and low thermal conductivity. The conventional flame-retardant CPCMs typically suffer from a functionally segregated architecture, while the PCM, support matrix, flame …

Surface modulation of two-dimensional perovskite for spatially selective p-type doping in van der Waals stacked MoS2 toward high-performance homojunction photodetector

Junxiong Liu, Yueheng Lu, Kexin Liu, Zhimin Liang et autres

Homogeneous p–n junctions in two-dimensional transition metal dichalcogenides (e.g., MoS2) demonstrate significant potential in high-performance optoelectronic devices. However, achieving stable and controllable p-type doping in MoS2 remains challenging, hindering the construction of high-quality p–n homojunctions. Traditional doping methods such as chemical adsorption …

A Simulation Platform for MARL Training and Evaluation in Swarm Confrontation

Qizhen Wu, Lei Chen, Kexin Liu, Jinhu Lü

In swarm confrontation, robots must swiftly formulate strategies in transient environments, a challenge well-suited for multi-agent reinforcement learning (MARL). However, existing platforms suffer from the lack of comprehensive confrontation scenario modeling and scalable frameworks, hindering MARL's widespread applications. We introduce a novel …

Research on the Impact of Carbon Emission Trading Policy on Carbon Emissions: An Empirical Examination Based on 284 Prefecture-level Cities in China

Hao Li, Yuxiao Lei, Nuo Li, Nuo Wang et autres

This study leverages the implementation of China's pilot Emissions Trading Scheme (ETS) policies as a quasi-natural experiment. Utilizing panel data from 284 prefecture-level and above cities in China spanning 2003 to 2017, we employ a multi-period difference-in-differences (DID) approach to empirically investigate …

The 36 Cl Bomb‐Pulse in Ice at a High‐Accumulation Site in Antarctica

L.K. Fifield, David Etheridge, Masayo Tada, Kexin Liu et autres

Abstract The radioisotope 36 Cl was produced prolifically by nuclear weapons testing, principally at Bikini and Enewetak Atolls in the 1950s. Much of this was injected into the stratosphere, from where it was dispersed worldwide. The fallout of this bomb‐produced 36 Cl …
